While vending machines provide convenience for hungry students, they often contain unhealthy junk food that can contribute to obesity and disease. They also use a significant amount of electricity and may distract from learning. However, vending machines offer variety and allow students to easily grab food. The document concludes by suggesting campuses should offer healthy snacks instead of junk food in vending machines and turn them off at certain times to conserve energy.
